If you're wondering how this fits into Amazon's portfolio, then you're in for a real suprise when you see their Presidential Candidates page.

No, you can't buy a president. (Well, one can buy a president of course, but you can't. Not at Amazon's discount prices anyway.) You can however donate to a political campaign. Nice to see Kerry/Edwards has raised about five times as much as Cheeny/Bush. Is Amazon more popular among lefties?
